目的 :了解河北省恙虫病疫源地的传播媒介与宿主。方法 :1998年 8月至 1999年 1月 ,对太行山区某恙虫病流行村定期捕鼠和分离恙螨 ,采集老鼠的肝脾和恙螨传代昆明种小鼠 ,取传代鼠肝脾涂片进行姬姆萨染色和切片进行免疫荧光法检测Rt,对采集鼠和传代鼠采血检测血清恙虫病抗体。结果 :褐家鼠和黑线姬鼠为当地的优势鼠种 ,无论采集鼠和传代鼠的血清中均查到恙虫病抗体 ,传代鼠的肝脾涂片和切片均查到恙虫病立克次体。传播媒介为小板纤恙螨 ,在其传代标本中也发现恙虫病抗体和立克次体。结论 :河北省恙虫病疫源地宿主为褐家鼠和黑线姬鼠 ,媒介为小板纤恙螨
Objective: To understand the vectors and hosts of tsutsugamushi disease in Hebei Province. Methods: From August 1998 to January 1999, the mice were caught and segregated chigger mites regularly from the endemic village of tsutsugamushi in the Taihang Mountains. The hepatocytes, spleen and chigger mites were collected from Kunming mice, Giemsa staining and sections were detected by immunofluorescence Rt, collection of mice and passaged blood staphylococcus tsutsugamushi antibody detection. Results: Rattus norvegicus and Apodemus agrarius were dominant rodent species in the area, both were found in the sera collected from mice and passage rats, and were found in the liver and spleen smears and sections of passage rats body. Vectors for small plate chigger mites, in its passage specimens also found scrub typhus antibodies and rickettsia. Conclusion: The hosts of tsutsugamushi disease in Hebei Province are Rattus norvegicus and Apodemus agrarius, and the vectors are small chigger mites
